Mr maxwell is shipping 80 video games each box will hold 12 games how many boxes will be needed

7 boxes will be needed.

Step-by-step explanation:

7x12=84. So enough room but with some space left.

6 is not enough. 6x12=72. Which will not hold 8 of the games.

Around seven boxes.

Step-by-step explanation: In each box, there will be 12 video games and there are 80 video games in all, so all you have to do is divide 80 by 12, but you get 6.6666... So estimate. 6 times 12 equals 72, and 80-72 equals 8, so 6 boxes will hold 12 video games and the 7th will hold 8

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

13.46

step-by-step explanation:

16.80 x .20 = 13.46
